The WM_DEVMODECHANGE message is sent to all top-level windows whenever the user changes device-mode settings.

A window receives this message through its WindowProc function. 

Notifies an application of a change to the hardware configuration of a device or the computer.

A window receives this message through its WindowProc function. 

The device context is updated from the information specified in the Windows DEVMODE structure. This member function only resets the attribute device context.

An application will typically use the ResetDC member function when a window processes a WM_DEVMODECHANGE message. You can also use this member function to change the paper orientation or paper bins while printing a document.

You cannot use this member function to change the driver name, device name, or output port. When the user changes the port connection or device name, you must delete the original device context and create a new device context with the new information.

Before you call this member function, you must ensure that all objects (other than stock objects) that had been selected into the device context have been selected out.

CEdit::SetLimitText

void SetLimitText( UINT nMax );

Parameters

nMax

The new text limit, in bytes. 

CEdit::LimitText

void LimitText( int nChars = 0 );

Parameters

nChars

Specifies the length (in bytes) of the text that the user can enter. If this parameter is 0, the text length is set to UINT_MAX bytes. This is the default behavior.
